' Eight specimens. 



'^ Five specimens. 



^ A nest and eggs, with the female parent, collected at Banff in June, 1898, were sent 

 to me for identification by Mr. Charles E. Doe, of Providence, R. I. 



•All these supposed records from east of the Missouri River are more or less doubt- 

 ful, except that pertaining to Laurel, Maryland, which alone has been seen by me 

 since the present form was differentiated. Some of them — possibly all — may be 

 referable to /. oreganus shufeldti. 



5 Many of the records queried above may belong to ./. oreganus xhufeldti, but not 

 having seen the specimens on which they are based, I have thought best to place • 

 them under /. montanus provisionally.
